  1. Disconnect the sensor connector.

  1. Measure the resistance of the sensor.

    Standard resistance:
    Tester Connection
    		Condition
    		Specified Condition
    1 (HT) - 2 (+B)
    		20°C (68°F)
    		10 to 16 Ω
    1 (HT) - 4 (+B)
    		20°C (68°F)
    		10 kΩ or higher
    If the result is not as specified, replace the sensor.
